I accessed my season tickets today, but I only attempted to download the parking and game tickets for Fort Hays on November 7. I was able to download both of them successfully and save them to Google Pay on my Android phone. They both worked. However, there was one oddity: the parking ticket said it was for November 1, whereas the game ticket had the correct date of 11/7.
This is way better than my experience during the summer with my Connecticut Sun season tickets, which never really worked with Google Pay. Mohegan Sun was very helpful, and sent me links to access a scannable image of the ticket for each game, and I could use that to gain admission.
The UConn tickets appear to be scannable and should work straightforwardly when I attempt to go to the Fort Hays game (except for that date glitch regarding the parking).
